Abstract

Nowadays, the Brazilian poultry industry is the third in the world raking in production of chicken meat, stating in 2010 the amount of 12.23 million tones. The consumption of animal protein increases every year, in 2009, the consumption per capita was 38.47 kg/year and in 2010, this value increased 44.09 kg/year (ABEF, 2011).Due to the increased consumption of poultry meat, it should be noted concern about the transmission of harmful pathogens to human health. The proper hygiene during the processing, storage and handling of food is the best method to avoid transmission of pathogens (PINTO, 1996).The main important pathogens found in poultry slaughterhouse are Clostridium spp., Listeria monocytogenes, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus cereus, and microorganism of Enterobacteriaceae family, like Salmonella Typhimurium, Escherichia coli, Yersinia enterocolitica, etc. All this agents are responsible by intestinal illness an economical spends although the risk for healthy elders and children (MAROUANI-GADRI et al., 2009). Base on this data, the aim of this study is evaluate the use of water spray under pressure as a operational form of microbial control, analyzing the number of pathogenic bacteria present in conveyor in poultry processing before and after hygiene. The analysis will be performed through quantification of Enterobacteriaceae and Clostridium spp. and isolation of Salmonella spp., Clostridium perfringens and Escherichia coli. After the use of traditional methods will be made PCR and identification of strains by PFGE technique. (AU)
